P. DIDDY JOINS CAST OF ‘DOWNTON ABBEY’

Sean "Diddy" Combs pulled a nice promo prank on his over 8-million Twitter followers Wednesday when he tweeted, "MY BIG NEWS: So happy to announce that Im a series regular on DOWNTON ABBEY-my favorite show+i'll be debuting a sneak peek tonight 12am PST!"

The Twitterverse, naturally, went nuts. "Downton Abbey" did recently announce the casting of its first recurring black actor (that would be actor Gary Carr) -- but for a few minutes there it seemed they might be expanding the diversity of the cast.

Alas, 'tis not so. Not officially so, anyway.

"It's not true," PBS spokeswoman Carrie Johnson told Reuters in an email.
